Title: BiCMOS local address transition detection circuit
Inventor: GABILLARD BERTRAND
IPC: G11C8/18
Filed: 1991-07-31
Abstract: A plurality, one per address bit signal (Ai), of local address transition detector (LATD) circuits are conventionnally used in SRAMs to generate an on-chip clock pulse (LATDSi) that insures a correct timing of some internal circuits such as sense amplifiers and address decoders that are essential for a correct READ/WRITE operation of the SRAM. For its operation a LATD circuit according to the present invention requires true and complement input address signals (Ai',  Ai '; Ai*',  Ai *') respectively at the ECL and CMOS voltage levels . According to a preferred embodiment it includes: a first bipolar transistor (T1) serially connected with a first FET device (N1) forming a first branch; a second bipolar transistor (T2) serially connected with a second FET device (N2) forming a second branch. Said first and second branches being connected in parallel between a first supply voltage (Vcc) and a common output node (N) connected to a circuit output terminal (30-i) where the output signal (LATDSi) generated by the LATD circuit (22-i) is available. Said first and second bipolar transistors (T1, T2) are respectively driven by the address signal (Ai') and its complement (Ai') at the ECL voltage levels and said second and first FET devices are respectively driven by the address signal (Ai * ') and its complement ( Ai *') at the CMOS voltage levels. 
     The LATD circuit (22-i) further includes a stand-by circuit (27) connected between said common output node (N) and said second supply voltage (Vee); a pull-down circuit (28) connected between said common output node (N) and said second supply voltage; and, an amplifying and delay line circuit (29) connected between said common output node (N) which drives said pull-down circuit (28). 
     Preferably, these two pairs of signals at the ECL and CMOS voltage levels (Ai', Ai'; Ai * , Ai * ') are generated by a BiCMOS address buffer (21-i) which consists of three stages: an ECL receiver (21-i1) generating said Ai' and Ai' signals at the ECL voltage levels, a voltage translator (21-i2) and two output drivers (21-i3, 21-i3'), generating said Ai' and  Ai *' signals at the CMOS voltage levels. 
     Fast LATD circuits are highly desired in advanced high speed SRAMs to reduce delays in the critical access paths.

Abstract: A rail grinding machine (20) especially designed for grinding railroad track rails (34) at railroad track switches and road crossings. Railroad switches and road crossings present particular problems to the rail grinding process. Gaps are necessarily presented in the railroad switches to permit the wheels of a railroad car to cross over one or the other of a set of rails in the switch and at least one of the set of rails in a switch will be curved. An additional problem presented at road crossings as well as at railroad switches is the presence of obstructions close to the railroad. The grinding machine includes an articulated grinding module supporting undercarriage (26) suspended from the grinding machine main frame (22). The undercarriage includes a unique suspension system that allows for lateral shifting and pivoting of the undercarriage independently of the grinding machine main frame. Grinding operations are controlled by sensing the supply pressure of the constant flow hydraulic fluid used to power the individual grinding modules (158), and positioning the grinding modules in grinding abutment with the rails as a function of the supply pressure.

Abstract: A method of manufacturing a metallurgically monolithic integral heated probe for injection molding. An electrical terminal (80) and three portions (90,92,60) of the probe body are made and assembled together with an electrical heating element (72) extending in an aligned bore. The forward portion (90) is made of abrasion resistant high speed steel, while the rest of the probe body is made of hot work tool steel. A removable and reusable filler tube (132) is screwed into a threaded seat (88) in the rear cap portion (60) and a quantity of silver (136) is loaded into it. After a nickel alloy brazing material (131) is applied to the joins, the assembly is heated in a reduced oxygen atmosphere in a vacuum furnace according to a predetermined cycle. The nickel alloy seals all the joins and the silver braze fills all the spaces between the components to provide a metallurgically monolithic integral probe. Using silver which is more conductive and has a lower melting temperature than copper reduces the cycle time and avoids having to heat the assembly into the austenitizing range of the steel body.
